While your cover letter won't help in the initial selection process, it can distinguish you from the competition in the final rounds. If you're responding to a classified ad, try to use some of the key words the ad mentions.

Taking the time to put together a letter targeted to the position offered shows the employer that you are interested in this position, and not just any position that will bring home a paycheck. Remember, if you're sending your resume to a new networking contact, be sure to mention who referred you.

In the job search, many people tend to shrug off the idea of a cover letter as a mere nuisance. They're wrong! Ask any recruiter or hiring manager, and they're likely to tell you “no cover letter, no interview.” Even if you are sending your resume via e-mail, take the time to compose a compelling cover letter that sells your skills.

The cover letter also offers you the chance to fill in any holes in your resume. For example, if you've been out of the work force for several years, a cover letter offers you the opportunity to explain.

An effective cover letter should include the following five points:

1. Target the letter to the specific job you are applying for. If there is no specific job, then ask about employment possibilities.

2. Target the letter to the specific employer. Here's where your research will come in handy. Let the employer know that you know something about the company and/or its competitors.

3. Talk about a specific class or experience you've had that may be especially helpful in the proposed job.

4. Use names. If someone from the company recommended you, say so. If you've read about someone in the company, mention that this person is someone you admire and see as a role model.

5. Be enthusiastic. If you really want the job, it will be communicated to the reader and will enhance your chances of gaining an interview.

If you've taken the time to craft a letter that summarizes your strongest qualifications, you'll have the edge over other contenders who skip this important step.
